China's temporary anti-dumping duty on optical fiber from Europe and the United States

The Ministry of Commerce announced on the 9th that the preliminary decision was made to adopt temporary anti-dumping measures in the form of margin on non-dispersive-displacement single-mode optical fibers originating in the United States and the European Union, with interim deposits ranging from 4.7% to 29.1%.

According to the investigation report, it was determined that there was dumping in the non-dispersive displacement single-mode fiber during the investigation period, which caused substantial damage to China's domestic industries. There was a causal relationship between dumping and actual damage**. The preliminary decision was made since February 18. Starting from the day, when importing non-dispersion-displaced single-mode optical fibers, Chinese operators should provide corresponding guarantee deposits to the customs according to the dumping margin (4.7%-29.1%) determined by the preliminary decision.

Non-dispersive displacement single-mode fiber is the largest amount of optical fiber in the world today, accounting for about 70% of the total fiber consumption, and is widely used in high-speed, long-distance transmission, such as long-distance communications, trunk lines, cable television and loop feeder networks.

At present, China imposes 5% import duty and 17% import VAT on imported products originating in the United States and the European Union.

Wedge Prism

Wedge prism is an optical element having plane-inclined surfaces, usually the faces are inclined toward one another at very small angles. Wedges divert light toward their thicker portions.

Wedge prism is commonly used in laser system for eliminating the reflections from the second surface or for beam steering.circle wedge,square wedge,irregular wedge...Every materials,sizes,wedges and coatings may be available by custom orders. Standard and broadband antireflection coatings are available upon request.
